Researchers are investigating whether a change in diet could help patients with breast tumours after studies in mice showed that asparagine, a compound first identified in asparagus but present in many other foods, drives the spread of the disease to other organs.

When scientists reduced asparagine in animals with breast cancer, they found that the number of secondary tumours in other tissues fell dramatically. The spread of malignant cells, often to the bones, lungs and brain, is the main cause of death among patients who are diagnosed with breast cancer.
